About the M1V format
M1V is a bare MPEG-1 video elementary stream — the video of Video-CDs without any container. MPEG-1's 352x288 VCD resolution looks prehistoric now, but the decoder is built into literally everything, which is why the format refuses to die.
Elementary streams confuse modern players (no timestamps container), so the fix is wrapping into MP4 — the video decodes through ffmpeg and gains proper seeking.
+ Strengths
- ✓Plays on literally any hardware
- ✓Simple to decode — zero surprises
- ✓Common on old CD rips
! Limitations
- −VCD-grade resolution only
- −No timestamps without a container
- −No audio track inside M1V
About the 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+ Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
! Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it

Frequently asked questions
Is this M1V to 3GP converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for M1V to 3GP?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of 3GP, staying in sync with the video. If your M1V file has multiple audio tracks, the first one is used.
Does converting M1V to 3GP re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
